Geoscientists use satellite to determine not the shape of water, but how water shapes land
7+ mon, 2+ week ago (427+ words) Virginia Tech geoscientists are using the same satellite to ask a related question: How is water shaping the land? "We wanted to show how the satellite could be used in ways that it wasn't primarily designed for," said postdoctoral associate…...
ExoAnalytic tools to power FireSat wildfire monitoring constellation
7+ mon, 3+ week ago (384+ words) Under the new effort, ExoAnalytic will design and deliver containerized web applications that display satellite orbits and broad sensor coverage for the FireSat Earth observation constellation. The tools will depict 1,500 kilometer swath coverage, allowing users to visualize the areas the…...
Slow orbital wobble patterns drive ancient greenhouse climate swings
7+ mon, 4+ week ago (413+ words) Because Earth's rotation axis is tilted relative to its orbital plane, regions outside the tropics experience a single annual peak in solar radiation, near the local summer solstice. By contrast, tropical latitudes see two annual maxima in solar radiation near…...
Neural network sharpens satellite ocean color in complex coastal waters
8+ mon, 1+ week ago (673+ words) Tokyo, Japan (SPX) Jan 01, 2026 A recent study presents ACA-SIM, an atmospheric correction algorithm that uses satellite-in situ matchup data and neural networks to improve ocean color retrievals over coastal waters. The approach relies on real satellite radiance and in situ…...
Calcite deposit from southern Nevada cave reveals 580,000 years of climate history
9+ mon, 2+ week ago (672+ words) The findings, just published in the journal Nature Communications, provide new insight into the region's hydroclimate and how it may evolve in the future, said Kathleen Wendt, an assistant research professor at Oregon State University and the study's lead author....
Satellites and AI equip policymakers to assess global climate adaptation progress
9+ mon, 3+ week ago (336+ words) Berlin, Germany (SPX) Nov 15, 2025 A study led by the University of Galway's Ryan Institute details how satellite-based Earth observation and artificial intelligence enable objective monitoring of climate adaptation in the global agrifood sector. Researchers analyzed how Earth observation data can…...
Ancient mantle revealed by 3.7-billion-year-old rocks in Australia
10+ mon, 6+ day ago (147+ words) Lead author Matilda Boyce said the scarcity of ancient rocks makes determination of early crustal growth timing and rates challenging. The team applied fine-scale analytical methods to original plagioclase feldspar, capturing the isotopic composition of the ancient mantle. The evidence…...
First evidence of Ice XXI phase observed at extreme pressure and room temperature
10+ mon, 6+ day ago (443+ words) Over the last century, scientists have reported 20 crystalline ice phases by varying temperature and pressure. These include forms that exist across over 2,000 K and more than 100 GPa. The region between ambient pressure and 2 GPa is particularly complex, with over ten…...
Solar geoengineering faces daunting practical and political challenges
10+ mon, 3+ week ago (298+ words) "It isn't just a matter of getting five teragrams of sulfur into the atmosphere. It matters where and when you do it," McNeill noted. The team argues that a globally coordinated SAI effort would be essential to minimize harmful side…...
New U.S.-European Sea Level Satellite Will Help Safeguard Ships at Sea
11+ mon, 3+ week ago (216+ words) "Building on NASA's long legacy of satellite altimetry data and its real-world impact on shipping operations, Sentinel-6B will soon take on the vital task of improving ocean and weather forecasts to help keep ships, their crews, and cargo safe", said…...
